. PRINTERS STICK.

Application filed June 23, 1923. Serial No. 647,317.

To all whom it may concern.

Be it known that 1, JOHN H. JoNns, a citizen of the United States, and aresident of Sioux City, in the county of W'oodbury and State of Iowa,have invented certain new and useful Improvements in Printers Sticks, ofwhich the following is a specification.

My invention contemplates a printers composition stick embodying certainnovel 1 features of construction whereby the adjustable column wall, orknee, is readily ad ustable, yet positively secure, when locked, againstany tendency to move or spring laterally.

A further object of the invention is the production of a printerscomposition stick embodying the above feature, which is thoroughlydependable and durable in use, yet comparatively inexpensive inconstruc- Ltion.

These and other objects and advantages I successfully attain in theembodiment hereinafter described, defined in the appended claims andillustrated in the accompanying drawings which form a part of thisapplicavention.

tion and in which like characters of reference indicate correspondingparts throughout the several views, of which,

i Fig. 1 is a plan of a printers composition stick constructed inaccordance with my in- Fig. 2 is a front elevation thereof.

Fig. 3 is a rear elevation thereof.

Fig. 4 is a fragmentary plan of the same with the cover of the detentguide removed.

Fig. 5 is a transverse section of the same taken on the line 55 of Fig.4.

Fig. 6 is a fragmentary, horizontal section of one of the detents andassociated parts taken on the line 66 of Fig. 5, and

Fig. 7 is a horizontal section of the guide detent and associatedmembers taken on the line 77 of Fig. 5.

Referring now to the illustrations, the composition stick illustratedembodies the usual bottom or floor, 8, a rear flange, 9, and a fixed endflange, 10. Extending transversely across the floor of the stick is aguide member for two detent elements coacting with the racks on oppositesides of the stick. In the preferred embodiment the said guide member isa channeled plate, including a bottom, 11, and flanges, 12 and 13, thelatter being deeper than its companion to serve as the adjustable knee,or column wall. Wlthin the channel slide oppositely-disposed detentbars, 14. One of said bars, 14, has a downwardly-extending part, 15,depend ing below the bottom of the stick and having a laterally toothedpart, 16, engageable and disengageable with and from a rack, 17, on thebottom of the stick, 8, and adjacent the'unflanged edge thereof. Theother of said detent bars, 14, is provided with an upwardly-extendingpart, 18, which is extended rearwardly to overhang the flange, 9, of thestock, and a rack, 19, secured to the outer side of the flange, 9,adjacent its upper edge,

the overhanging portion of the part, 18, bevT9 ing provided with a part,20, which depends adjacent the outer side of the rack, 19, and isprovided with teeth, 21, engageable and disengageable with and from saidrack. The detent part, 20, is provided on its lower edge T: with a lip,22, which slidably engages the under side of the rack, 19, and theopposite detent part, 15, is provided with a lip, 23, which slidablyengages the under side of the adjacent rack. These lips serve to preventupward displacement of the detent mechanism from the stick.

The adjacent end portions of the detent bars, 14, are slotted as at 24,to receive retracting spring, 25, having its ends seeured, respectively,to a cross bar, 26, in the notches, 24. Thus, the spring, 25, holds thedetent members normally engaged with the racks. The detent guide body iscovered by a plate, 27, resting upon and secured to the flange, 12, by ascrew, 28, or otherwise. The detent members are controlled by suitablelevers, 29, fulcrumed as at 30, on the detent body and having dependingparts, 31, projecting through arcuate slots, 32, in the cover plate andinto the notches, 11, of the respective detent bars, 14, by virtue ofwhich construction it is clear that movement of the levers toward eachother will disengage the detents from their associated racks and permitadjustment of the bar, 13, longitudinally of the stick.

To further insure rigidity of the device, the bottom, 11, of the detentguide body is provided with an extension plate, 33, which plate isprovided with an upright flange, 34, slidably engaging the flange, 9,and formed at its upper edge with a U-shaped part, 35, which is hookedover the flange, 9, and the rack, 19.

lVhile I have illustrated and above described but one embodiment of theinven tion, I would not be understood as being limited to this specificconstruction, for it will be readily apparent that the device issusceptible of numerous modifications and alterations in the details ofconstruction and arrangement of parts without departing from the spiritand scopeof the invention as defined in the appended claims.

1. A printers stick embodying a floor having flanged and unfl'angededges, a rack on the outer side of the flange, a second rack on theunderside of the floor adjacent the uniianged edge thereof, a. blockmounted upon and movable longitudinally of the floor, a knee carried bythe block, toothed detent bars slidably supported by the block andmovable toward and from each other to accordingly engage and disengagetheir teeth from the racks, and levers ful'crumed on the block for thecontrol of the detent bars.

2. A printers stick embodying a floor having flanged andiuifi'angededges, a rack on the outer side of the flange, second rack on theunderside of the floor adjacent the unl'langed edge thereof, a blockmounted upon and movable longitudinally of the floor, a knee carried bythe block, toothed detent bars slidably supported by the block andmovable toward and from each other to accordingly engage and disengagetheir teeth from the racks, a yieldable link between the bars holdingthem normally en gaged with the racks, and levers iulcrulned on theblock for disengaging the bars from the racks.

8. A printers stick embodying a floor hav ng flanged and unflanged'edges, a rack on the outer side of the flange, a second rackf on theunderside of the floor adjacent th unfianged edge thereof, a channeledbodyf disposed transversely of and upon, n movable longitudinally of thefloor, one flange thereof serving as the knee ofthe stick, detent barswithin the channelfone thereof having a U-shaped part receiving theflange of the stick and its rack and provided with teeth engageable anddisengageable with and from the associated rack, and the other thereofhaving a depending toothed part engageable and disengageable with andfrom the other rack, and means for controlling the detent bars.

A printers stick embodying a floor having flanged and unfianged edges, arack on the outer side of the flange, a second rack on the underside ofthe floor adjacent the unfla'nged edge thereof, a channeled bodydisposed transversely of and upon, and movable longitudinally of theFloor, one flange thereof serving as the knee of the stick, detent barswithin the channel, one thereof having a U-shaped part receiving theflange of the stick and its rack and provided with teeth engageable anddisengageable with and from the associated rack, and the other thereofhaving a depending toothed part engageabl'e and disengageable with andfrom the other rack, and finger levers fulcrumed on said'body andoperatively connected with the detent bars to disengage said detent barsfrom the racks.

In testimony whereof, I have hereunto set my hand this 21st day of June,1923..

JOHN H. JONES.
